| Abstract: | Two single-head quaternary ammonium salts(1 and 2) were prepared from N,N′-dimethyloctadecylamine, 1,6-dibromohexane and 1-bromooctadecane, N,N,N′,N′-tetramethyl-1,6-diaminohexane, respectively.A trimeric quaternary ammonium surfactant(3) was synthesized by the reaction of 1 and 2.The structure was confirmed by 1H NMR and IR.The surface properties of 3 was investigated by conductance method and ring method.The results showed that cmc, γcmc and C20 of 3 are 0.01 mmol·L-1, 14.904 mN·m-1, 0.003 mmol·L-1 at 25 ℃, respectively. |
